Daimona Eaytoy b85f464530 Introduce a VariablesFormatter service
Moves more methods away from the AbuseFilter class. Testing
buildVarDumpTable is not easy because we'd have to parse the generated HTML.

Daimona Eaytoy c7f06750d6 Add a LazyVariableComputer service
See task for a description of the plan. Also note that
AFComputedVariable should be renamed and its properties made private.

This commit includes some adjustments for taint-check in
AbuseFilter::buildVarDumpTable and ::revisionToString.

There's some space for improvement in the new LazyVariableComputer, but
that's left for another commit.

Daimona Eaytoy 7bcb5ec2d5 Add a service to format filter specs
This requires a MessageLocalizer, which currently means providing the
main RequestContext. This is the only alternative right now, until core
provides a proper MessageLocalizer service (see T247127).

daniel dfeff89317 Use a BlobStore for storing var dumps
AbuseFilter emulates the storage mechanism also used for page content.
Instead of duplicating the relevant code, AbuseFilter should use the
same BlobStore service also used by RevisionStore.

Daimona Eaytoy 5e609eb537 Add GlobalNameUtils class
This is just a temporary location for these two methods. Since they're
used a lot, having them in the AbuseFilter class means that the
dependency graph is unnecessarily complicated. Thus, since these methods
aren't doing much, they were moved to a dedicated class. Future todo is
finding an appropriate location, that might be either as part of another
service, or keep them in a Utilities class, perhaps a single class with
all util methods, rather than a specific class.

Daimona Eaytoy 210cf29658 Add an interface for exporting/importing filters
The main benefit of having a dedicated interface is that we can easily
change the output format. So we're now using a custom array without
references to the DB schema, thus making the import/export process
completely independent from the schema.

Daimona Eaytoy 916234598d Simplify ViewEdit, last round
This deals with data inconsistencies in buildFilterEditor. Every
property of $row was tested in all 5 scenarios (also using Selenium) to
check when it's set. The result is in the normalizeRow method, which
aims to remove any inconsistencies, so that buildFilterEditor always
receives a "complete" row with all defaults set.

The code in buildFilterEditor is now cleaner (because there are no
isset() checks), and it gives us a unique place where we can set
defaults (rather than partly doing that in
loadRequest/loadFilterData/loadImport, and partly relying on isset).

This will be especially useful when introducing value objects to
represent filters, because now you just have to look at normalizeRow()
to tell which properties are allowed to be missing, and thus what "kind"
of filter object you need (see
I5f33227887c035e301313bbe24d1c1fefb75bc6a).

Additionally, reduce the properties that get passed around during
export/import, and make the selenium test try a roundtrip, rather than
relying on hardcoded data that may get outdated. A future patch will
refactor the import/export code.

Unfortunately, this isn't using DI completely, because of the
User::newSystemUser call. I'm not even sure if we really need to call it
or we can just stick to new UserIdentityValue, but leaving like this for
now.
Also, the types were weakened to UserIdentity, so the transition is
going to be easy anyway.

Daimona Eaytoy 416dcd9ba3 Simplify ViewEdit, round 2
- Add a helper method to output an unrecoverable error, comprising a
   button to go back to the filters list;
- Move the token check to attemptSave, so to make the conditionals
  easier to read, and group errors together
- Make buildFilterEditor take an HTML parameter for the error, so the
  caller can specify whether it's error or warning
- Move the check for non-existing filters out of buildFilterEditor
- Add a bunch of typehints
- Don't set af_throttled and af_hit_count in the empty row template, but
  set af_deleted (these are only used in buildFilterEditor)
- Make AbuseFilter::translateFromHistory consistently include the af_global
  property (previously it would only be set for global filters; this error
  was introduced when first implementing global filters)
- The only user-facing change is that, when trying to use a custom
  warning/disallow message on a global filter, this is now considered a
  non-fatal error, so we now show the editing interface (and not just an
  unrecoverable error).

The next step is resolving the @todo in buildFilterEditor about null
checks.

Daimona Eaytoy 9bc885b6b3 Add a ChangeTagger class
The logic about action IDs and the persistent buffer is now encapsulated
inside a single service, which is a step towards getting rid of global
state in the AbuseFilter class, and reducing the responsibilities of the
Runner.

An important change made here is that we now require a LinkTarget rather
than a Title. This removes a dependency on the Title class (a monster
object), makes tests simpler, and denies the need to inject a
TitleFactory. This means living without some bits of context (e.g. we're
no longer using makeTitleSafe to ensure a valid title, and we have to
build a "prefixedtext" manually), but this shouldn't be a problem, given
that the titles are only used to create a cache key: invalid titles are
not a problem, and concatenating namespace + title should always be
sufficient.

- Depend on a generic IContextSource rather than SpecialAbuseFilter
  (lower coupling);
- Inject a LinkRenderer (IContextSource doesn't have a ::getLinkRenderer
  method)
- Add a helper method in SpecialAbuseFilter to get the page title, that
  can also be used elsewhere (and the name constant can be made private
  now)
- Pull down the mFilter property (and rename it to just 'filter') to
  classes that actually need it. Some classes didn't need this at all
  and the types were different among subclasses

Now the only cause of coupling between the View classes and
SpecialAbuseFilter is the static call in getTitle.

Daimona Eaytoy f0539e0c1e Represent new filters with null instead of 'new'
PHP is not strongly typed, so it's not a good idea to use scalars of
different types (here it's an integer vs the string 'new') to represent
different possibilities. This can have bad effects when type juggling
occurs, and it's also harder to figure out what the type of the
parameter can be (because a numeric ID might have been passed as a
string). Using integer vs null avoids all of this, and also allows us to
use nullable typehints.

These changes were partly copied from
If981cb35bf19a8469aa6c43c907e107cf8c65bc2 and should help with the
migration to the Filter value objects.

Daimona Eaytoy 9f2906e34b Reduce dependencies of AbuseFilter::saveFilter
This patch removes the dependency of saveFilter on the ContextSource
kitchen sink. It also removes some unneded dependency, and adds
$originalRow/$originalActions as parameter, rather than hacky properties
in $newRow that are easy to forget. The related test can also be greatly
simplified.

This also introduces a behaviour change: checking $newRow instead of the Request allows us
to account for values normalization done in
AbuseFilterViewEdit::loadRequest, and to also work correctly for imports
(and generally speaking, it makes the method suitable for an
AbuseFilterEdit API module, too).

Next step is moving this method to a service. Some signatures,
indenting, name choices etc. are subpar, but this is just because these
methods are temporary anyway.

Daimona Eaytoy 11d922d1bd Remove useless param to wfMessage
Copying my investigation from I8c93e2ae7e7bd4fc561c5e8490ed2feb1ef0edc2:

This code was introduced in 2009, see rEABF0f1eb8db78bfa83ddb93427f39aad619523d8f25:

  $display = wfMsg( "abusefilter-action-$action" );
  $display = wfEmptyMsg( "abusefilter-action-$action", $display ) ? $action : $display;

And wfEmptyMsg looked like this:

  function wfEmptyMsg( $msg, $wfMsgOut ) {
    return $wfMsgOut === htmlspecialchars( "<$msg>" );
  }

so this made sense. But then, in 2010 (rMWae3ced88e535c7fd046f0ad6f0710cc87f0004ea) the function was changed:

  function wfEmptyMsg( $key ) {
    global $wgMessageCache;
    return $wgMessageCache->get( $key ) === false;
  }

without anyone removing the parameter from AbuseFilter.

Finally, in 2012 (rEABF176227e721c9475de2c2163d3b6e20ca4769c406) the usage of wfEmptyMsg was removed, and $display became a parameter to wfMessage().

Long story short, no need to pass that parameter.

- Include an attempt to restore the dump in case the text table
   contains a truncated dump (not 100% sure that this can really
   happen, nor do I know the cause, but it shouldn't hurt)
 - Remove a check for 'action'. The variable might be missing in case of
   a corrupted dump. Having an array at that point can only mean "new
   format".
 - Don't assume that old_wikitext and new_wikitext are set when showing
   past filter hits (again, might be unset due to data corruption).
